When you export a file in PostScript format as an EPS file, some AutoCAD LT objects are specially rendered.
Text, attribute definitions, attributes: If you specify the font file for converting the text objects in the font substitution map of the PostScript support file aclt.psf, AutoCAD LT plots the text using the PostScript font you specified. Otherwise, AutoCAD LT renders the text using outlined characters. The aclt.psf file must be in the support directory specified in the Preferences dialog box.
Thickened text, text control codes: If AutoCAD LT text has a thickness greater than 0 or contains control codes (such as %%O or %%D), it is not plotted as PostScript text, although the text is accurately rendered. International and special symbols (such as %%213) are output as PostScript text.
ISO 8859 Latin/1 character set: When AutoCAD LT text uses character codes in the 127 to 255 range, the text is interpreted according to the ISO 8859 Latin/1 character set. If such a character appears in text that is mapped to PostScript, AutoCAD LT generates a version of the font with an encoding vector remapped to represent the ISO character set. The resulting text is output in PostScript in a form compatible with the font.
Circles, arcs, ellipses, elliptical arcs: Except when they have thickness, AutoCAD LT translates arcs and circles into the equivalent PostScript path objects. This translation occurs regardless of the projection in effect in the active view when you use PSOUT.
Block references: When a block reference (insertion of a block) includes extended object data indicating it was created in AutoCAD using PSIN, the AutoCAD LT geometry associated with the block is bypassed and replaced by a transcription of the original PostScript code imported into the AutoCAD drawing using PSIN.
Filled solids: A solid fill is plotted as a PostScript filled path.
Two-dimensional polylines: A 2D (planar) polyline with uniform width is output as a PostScript stroked path. The PostScript end cap and miter limit variables are set to approximate the segment joining performed by AutoCAD LT.
